Quality Windshield Wipers
Size: 17", Style: Latitude Repellency
These wipers are a solid upgrade over standard blades. Installation is quick and straightforward, and they fit securely once attached. On the first use, you can immediately notice the difference the wipe is smooth and consistent with very little streaking. The Rain-X water-repellent feature actually works, helping water bead up and roll off the windshield for better visibility during heavier rain. They also run fairly quiet compared to cheaper blades, which is a nice bonus.

Does what it says
Size: 22" and 22", Style: Latitude Repellency
These are my favorite wiper blades. They install easily on my Dodge Challenger and work well as wipers. But I like the little bit extra of RainX repellency to help water bead off my window in between wiper swipes.

Not streaky!
Size: 26" and 17", Style: Latitude Repellency
These work really well! They are not streaky, which was the biggest thing I was hoping for! They also aren’t too noisy, thankfully! They were easy to install too! I have only used them for a couple of months and so far they have continued working well!

Good wipers
Size: 22", Style: Latitude Repellency
Bought these wiper blades because my wiper blades were old. The new blades lay down a good level of water repellent on the windshield. I actually drove home this morning in a rainstorm and purposely did not turn on my wipers once, and the windshield stayed nicely beaded and cleared, a month after I put the new wipers on my truck. I recently bought my s/o a set for her vehicle. They’re expensive, but seem to be worth it. Very quiet, no chattering, 30 seconds to install on my F150.
